To Save the Change to the Holding Register (enter command)
Even if using the command to write into the holding register (06h) or into the consecutive holding
registers (10h), no change can be saved in the EEPROM memory element of the Inverter. If the
Inverter power shuts off without saving any changes, the holding register returns to the status before
the changes were made. To save the holding register changes in the Inverter's EEPROM memory
element, the "enter command" must be issued according to the following procedure.
To issue the enter command
Write into all memory write (holding register number 0900h) using the writing command into the
holding register (06h). In this case, a random value can be written into the holding register (0900h).
Notes:
•The enter command needs considerable time. Monitor the data writing signal (coil number 001Ah)
to check whether the data is being written.
•Since the Inverter's EEPROM memory element has a limit on the number of rewrites (approx.
100,000 times), the Inverter life may be shortened if enter commands are frequently used.
